To all whom it may concern.-

Be it known that l, `CHARLES W. SPENGLER, a citizen of the UnitedStates, residing at .l effersonville,'in the county of Fayette and Stateof Ohio, have invented a new and useful Wrench-Operating Mechanism, ofwhich the following is a specification.

This invention relates to Wrench-operating mechanism particularlyadapted for use in turning nuts'on boltssuch 'as are used to sea deviceto eject the nuts from the wrench.

' and. particularly pointed out in the claims.

` together by bolts 2.

In the drawings, Figure 1 is a side elevation of my improvedwrench-operating mechanism, the casing being in section, showing oneform of the connecting devices between the operating-shaft and. thewrench carrying shaft. Fig. 2 is an end view. Fig. 3 is a similar Viewlooking at the other end of the device, the casing being broken awayl toshow the gearing. Fig. 4 is a view similar to Fig. 1, showing anotherform of connecting device between the operating-shaft and thewrenchcarrying shaft, the connecting device being partly broken" away.Fig. 5is a perspective view of the connecting device for the shafts.

Fig. 6 is a longitudinal section through the wrench-head, showing themanner of mounting the nut-ejector. Fig. 7 is a perspective View of theejector detached.

Similar reference-numerals indicate similarparts in the several figures.

Referring to Figs. 1, 2, and 3, 1 indicates a hollow casing formed intwo sections separable on a vertical line, detachably connected Thecasing is provided withtalining openings 3 in its opposite sides toreceive and form bearings for the respective hubs 4 and 5 of the gears 6and 7. The

gear 6 will preferably be of less diameter than 5 5 the gear 7 in orderthat it may rotate faster. Each hub will preferably have shoulders 8 toengage theinner faces of the casing and prevent longitudinal movement ofthe hubs inff# The gears 6 and 7 are fast on 6o their bearings.

the hubs and rotate with them. 1 Y

The hubs- 4 and 5 Iare each provided with a longitudinal angular bore 9to receive, re-

' spectively, the wrench-shaft 10 and the operating-shaft 11, and theseshafts are supported in the hubs to slide freely therein, but to have norotary movement in the hubs.

12 indicates the wrench-head, secured on one "end of the shaft 10 andprovided with an angular opening 13 to receive the nut to be 7o turned.If preferred, the wrench-head may be detachably connected to the shaft10 in order that the head 'may be changed, if necessary, to adapt thedevice for use with nuts of different sizes. 10 is rounded and providedwith an annular groove 14, and this rounded end fits loosely in a socket15 and is held therein by a setscrew 16, which extends into the annulargroove and permits free rotary movement of 8o the shaft in the'socket,but prevents it from being withdrawn therefrom. The corresponding end ofthe shaft 11 is also rounded and l provided with an annular groove 17,and the rounded end fits loosely in a socket 18, similar to the socket15, and is held therein by a set screw 19 in a manner similar to thatdescribed with reference to thev shaft 10. Each socket is provided witha pair of spaced ears 20 for a purpose which will be referred tohereinafter. 9o

21 indicates an arm,preferably integral with the casing, although it maybe secured thereto in any other manner, if preferred, and this armextends horizontally from the casing. 22

indicates a lever or yoke pivotally connected The other end of the shaft7 5 The 10o lVhen the yoke is rocked on its pivot, the blocks will slidein the openings 24, and as the sockets are pivotally connected to theblocks the parts will adjust themselves when the yoke is rocked ineither direction by the longitudinal movement of the shafts. Theopposite end 27 of the shaft ll is shaped to receive an ordinarybit-brace, by means of which the shaft may be turned, or it may beturned by any other suitable device. The casing is provided with a ange23 at its lower end, through which bolts or screws 29 are adapted topass to secure the casing to any suitable support.

Referring now to Figs. 5 and G, it will be observed that the parts ofthe machine are similar to those already described, except as to theform of the ends of the shafts l0 and 1l and the yoke connecting them.In this form each shaft is provided with a ball 30 on its end and anarrow neck portion 3l between the ball and body of the shaft. The yokeis in the form of an open-ended tube, (indicated by 32,) the interiordiameter of which is substantially equal to the diameter of the balls30, which are intended to fit loosely therein. The tube is provided witha slot 33 at one side, extending from end to end and with anoutwardlyprojecting flange 34 at each side of the slot. Midway theirlength the flanges are widened to form the ears 35, which areperforated, as indicated at 3G. The end of the arm 2l projects into thetube between the ears 35, and the pivot-bolt 23 extends through saidears and the arm 2l. The balls 30 are inserted into the tube at itsrespective ends, and the necks 3l on the shafts will extend through theslot 33 and between the iianges 34, and it is evident that the yoke willbe free to adjust itself on the balls 30 when it is rocked on the pin 23by the horizontal movement of the shaft and that the balls can turnaxially in the yoke. The balls 30 form pivotal connections between thelever or yoke and the shafts l0 and 11, and the pivotal connection isadapted to move freely longitudinally of the lever or yoke.

Referring now to Figs. 5 and 6, it will be seen that the nut-ejectorcomprises arectangular block 37, from opposite sides of which a pair ofarms 38 extend rearwardly, the outer ends of these arms being bent toform lateral projections 30. The block 37 is adapted to work loosely inthe opening 13, and the arms 3S in grooves 40, in the wrench-head, andthe severa-l parts will be so proportioned that when the lateralprojections 39 engage the rear end of the wrench-head the front end ofthe block 37 will be flush with the front end of the head, as shown inFig. 5.

In operation the wheel will be supported in a horizontal plane in suchmanner as to enable the wrench l2 to fit over the nuts of the tire-boltssuccessively, and by turning the shaft ll rotary movement will beimparted through the gears 7 and 6 to the shaft l0 and the wrench-headl2, and it is obvious that this rotary movement may be in eitherdirection to turn the nut on the bolt or turn it off, as desired. Vhenturning the nut on the bolt, the shaft ll will be pushed forward towardthe pivoted yoke, and the yoke will thus be rocked on its pivot and movethe shaft l0 in the opposite direction, thereby causing the wrench-headto follow up the nut as it is turned onto the bolt. In turning the nutoil the bolt the nut will cause the shaft l0 to grad ually retreat infront of it, and this movement of the shaft will rock the pivoted yokeand move the shaft 1l in the opposite direction. When the nut has beenremoved from the bolt, the ejector will have been forced rearwardly, andby pulling on the shaft ll the lateral projections 39 will be caused toengage the hub 4, and the ejector will move toward the open end of thewrench-head and eject the nut.

It will be understood that changes in the form, proportion, and theminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim isl. In awrench-operating mechanism, the combination with an operating-shaft, anda wreneh-carryingshaft both su pported to have rotary and longitudinalmovement, of gearing to transmit rotary movement from one shaft to theother, and a lever fulcrumed between its ends and pivotally connectedwith the shafts, whereby the shafts are simultaneously reciprocated inopposite directions, substantially as described.
